This study aimed at investigating the effect of a proposed EFL (English as a Foreign Language) training program on the teachers' reading practices in Mafraq. This program was developed by the researcher according to the ninth-grade EFL teachers' needs. The participants of the study were 20 ninth-grade females EFL teachers who represented the experimental and control groups (10 teachers in each group). They were randomly chosen from 10 schools in the Northwestern Badia Directorate of Education. To achieve the purposes of the study, the researcher designed a needs analysis questionnaire, a training program, a pre and post observation checklist, and a pre and post received knowledge test for teachers. Proper statistical analysis was used to analyze the results of the research questions. The results of the study showed that teachers were in need to be trained on 20 reading comprehension practices to be able to teach reading comprehension effectively. Besides, there were statistically significant differences at the level of (a = 0.05) between the means scores of the ninth-grade teachers' performance of the control and experimental groups on the post observation checklist and on the post received knowledge test in favor of the experimental group due to the training program. 展开更多
